( [id://3333]=superdoc: print w/replies, xml ) Need Help??

It works great, but I don't fully understand why. It even works better than specified in my post, because I want the compiled SDK files in a subdirectory. This is my working test dummy:

default: all all: exe clean: rm -f foo.obj bar.obj sdk-objects/baz.obj main.obj exe %.obj: $(filter %.src,$<) @mkdir -p "$(dir $@)" @echo "Compile $< to $@" cat $< > $@ exe: main.obj foo.obj bar.obj sdk-objects/baz.obj @echo link $^ to $@ cat $^ > $@ main.obj: main.src foo.obj: subdir/foo.src bar.obj: subdir/bar.src sdk-objects/baz.obj: /tmp/baz.src

It just does what I mean! But how does it work? The filter function should just return $< - but at that point, the filter function has processed the source pattern %.src, so the rule is no longer a simple pattern rule. And then, something magic happens ... ;-)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
